5.9

Medium

Base vector

AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N

Name of the Vulnerable Software and Affected Versions: OpenPGP (affected versions not specified)

Description: The issue allows a Cipher Feedback Mode (CFB) malleability-gadget attack that can indirectly lead to plaintext exfiltration. This is reportedly a problem in applications that mishandle the Modification Detection Code (MDC) feature or accept an obsolete packet type, rather than an issue with the OpenPGP specification itself.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
